Precautions to keep in mind

If you will be taking this medicine for a long time (for example, for several months at a time), your doctor should check your progress at regular visits

For nursing mothers taking a codeine-containing medicine or any other narcotic analgesic:

• Call your doctor if you become extremely tired and have difficulty caring for your baby.
• Your baby should generally nurse every two to three hours and should not sleep more than four hours at a time.
• Check with your doctor or hospital emergency room immediately if your baby shows signs of increased sleepiness (more than usual), difficulty breast-feeding, difficulty breathing, or limpness. These may be symptoms of an overdose and need immediate medical attention.

Narcotic analgesics will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; other prescription pain medicines including other narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Do not drink alcoholic beverages, and check with your medical doctor or dentist before taking any of the medicines listed above, while you are using this medicine.

This medicine may cause some people to become drowsy, dizzy, or lightheaded, or to feel a false sense of well-being. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert and clearheaded.

Dizziness, light-headedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem.

Nausea or vomiting may occur, especially after the first couple of doses. This effect may go away if you lie down for a while. However, if nausea or vomiting continues, check with your medical doctor or dentist. Lying down for a while may also help relieve some other side effects, such as dizziness or light-headedness, that may occur.

Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are taking this medicine.

Narcotic analgesics may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.

If you have been taking this medicine regularly for several weeks or more, do not suddenly stop using it without first checking with your doctor. Your doctor may want you to reduce gradually the amount you are taking before stopping completely, in order to lessen the chance of withdrawal side effects.

If you think you or someone else may have taken an overdose, get emergency help at once. Taking an overdose of this medicine or taking alcohol or CNS depressants with this medicine may lead to unconsciousness or death. Signs of overdose include convulsions (seizures), confusion, severe nervousness or restlessness, severe dizziness, severe drowsiness, slow or troubled breathing, and severe weakness.
